Answer: х=24, у=20,8.
Step-by-step explanation:
Since it is a right triangle therefore:
[tex]\displaystyle\\1)\ sin30^0=\frac{12}{x} \\\\\frac{1}{2} =\frac{12}{x}\ |*2x\\\\x=24.\\\\2) \ According\ to\ the\ Pythagorean\ theorem:\\\\y^2=24^2-12^2\\\\y^2=576-144\\\\y^2=432\\\\y=\sqrt{432}\\\\y\approx20,8.\\[/tex]
